Unexpected Speed Limit In Path-Following via PYTHON API

I have been using Python API to simulate some vehicles to follow some predefined paths. However, the PYTHIN API function

API.FollowPathVehicle(veh_desc.id, path_desc.id, 1)

imposes some limits on the vehicle speed which could not be observed from ANVEL GUI. For example, the vehicle Coroware Explorer has a speed limit of 0.68 m/s while its speed could be much higher if run from ANVEL GUI (interactive mode) . Running the attached script and a exception is thrown out:

The current roadmap for ANVEL development includes plans for semiannual releases. Since our 2.0 release was in May 2017, we are working towards November 2017 as our next free/publicly available version.

Of course, paying customers will always have "early access" to betas and targeted bug fixes!
